In 2007, project planning began on a house built to the Passive House (PH) standard, in Urbana, Illinois. The project was initiated by the Ecological Construction Laboratory (e-co lab), a nonprofit community housing development organization interested in bringing the PH standard to the United States. It became a joint research effort when IBACOS was brought in to lead instrumentation and monitoring through DOE’s Building America program. (For more information, see “About IBACOS.”)
